Question

What is the most obvious sign of bias in a historical text?

Answer 1

Your teacher may have told you something specific that they want you to write here. If not, I would say it would be the glorification or demonization of any historical figure. Worshiping a certain figure by giving them constant praise and attempting to excuse every one of their immoralities, or showing a hatred of a certain figure by emphasizing their immoralities and attempting to belittle or invalidate their good deeds and accomplishments.  

Answer 2

Lack of accuracy on Facts.

Step-by-step explanation:

Taking into consideration the question about obviousness and the type of text, the lack of accuracy is one of the most significant bias one can see in any historical text.

When we talk about history, it requires a vast ammount of details including dates, places and even some info about possible occurred events. But when a text does not completely give this information with exact accuracy it leads the reader to have more questions to be answered rather than a full text comprehension.
